(DOC) VAT LEACHING AND ELUTION PLANT GOLD

Picture 4: Color test to confirm presence of gold In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction. Vats usually do not contain much internal equipment, such as agitators, baffles hence aeration is limited and therefore oxygen which is important for gold dissolution.

Day 51, Procedures to obtain gold: Vat Leaching

2013-7-29  Vat leaching also contains an environmental advantage over heap leaching. The footprint of a vat plant is much smaller than that of a dedicated heap-leach operation, even when considering disposal of vat tailings. A smaller treatment area also leads to plant simplicity and reduced cost of material transport. The main disadvantage to vat leaching
